MAT_DATE_FORMATS definition/meaning of fields
提问by Abhishek Jha
Material example for customizing-the-parse-and-display-formatsfor date picker uses custom MAT_DATE_FORMATS
日期选择器的自定义解析和显示格式的材料示例使用自定义 MAT_DATE_FORMATS
export const MY_FORMATS = {
parse: {
dateInput: 'LL',
},
display: {
dateInput: 'LL',
monthYearLabel: 'MMM YYYY',
dateA11yLabel: 'LL',
monthYearA11yLabel: 'MMMM YYYY',
},
};
I could not find where and how these fields like dateA11yLabelwill come into play. What I could figure out was display.dateInputis used in displaying selected date on calendar and display.monthYearLabelis used in the select drop-down of year selector.
我找不到这些领域dateA11yLabel将在何处以及如何发挥作用。我能弄清楚的display.dateInput是用于在日历上显示所选日期并display.monthYearLabel用于年份选择器的选择下拉列表。
- Where are rest of the fields used?
- When writing custom MAT_DATE_FORMATS is it mandatory to define all fields?
- 其余的字段在哪里使用？
- 编写自定义 MAT_DATE_FORMATS 时是否必须定义所有字段？

Well, I figured out the following:
好吧，我想出了以下几点：
parse: {
dateInput: 'DD.MM.YYYY',
},
display: {
dateInput: 'DD.MM.YYYY',
monthYearLabel: 'MMM YYYY',
dateA11yLabel: 'LL',
monthYearA11yLabel: 'MMMM-YYYY',
},
with
parse.dateInput: you can let the user enter any type of date with any format, and the date adapter will reformat it to the format you specify in this attributewith
display.dateInputyou can specify the input date format (marked with 1)display.monthYearLabelyou can specify the area marked with 2
with
parse.dateInput：您可以让用户以任何格式输入任何类型的日期，日期适配器会将其重新格式化为您在此属性中指定的格式与
display.dateInput您可以指定输入的日期格式（标有1）display.monthYearLabel您可以指定标有 2 的区域
unfortunately, I still don't know about the rest!
不幸的是，我仍然不知道其余的！

A11Y - means accessibility. Look here https://material.angular.io/cdk/a11y/overviewand here https://material.angular.io/components/datepicker/overview#accessibility
A11Y - 表示可访问性。看这里https://material.angular.io/cdk/a11y/overview和这里https://material.angular.io/components/datepicker/overview#accessibility
According that I think these formats are used to display datepicker when accessibility mode on.
据此，我认为这些格式用于在无障碍模式下显示日期选择器。
